MACHINE FOR CALKING SEAMS.

Application filed December 10, 1917. Serial No. 206,525.

To all whom it may concern:

Be it known that I, JOSEPH D. DENBUR- GER, a citizen of the United States, residing at Lents, in the county of Multnoniah and State of Oregon, have invented certain new and useful Improvements in Machines for Calking Seams, of which the following is a specification.

This invention relates to calking machines for calking the seams of ships and the like.

The main object of the invention is to provide a simply constructed and efficient machine of this character which while compact and easily handled is yet quite as effective if not more so than those of more bunglesome construction.

Another object is to so construct a machine of this character that it may be used for calking seams on both the deck and the outside of the hull of a ship and which may be also used for calking seams on any other structure.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a front elevation of a machine constructed in accordance with this invention,

Fig. 2 represents a longitudinal vertical section taken on the line 2-2 of Fig. 1,

Fig. 3 is a top plan view thereof on a small scale, and

Fig. dis a horizontal section taken on the line H of Fig. 1.

In the embodiment illustrated, a casing 1 is shown having a tubular upright 2 depending therefrom and on which it is supported. A pair of oppositely disposed arms 3 and 4 are carried by the lower end of the tubular upright 2 and are here shown arcuate in form although obviously thev may be of other desired configuration. These arms are bifurcated at their lower ends and between the furcations 5 thereof are mounted wheels 6 which have knife edges 7 which adapt them to travel in the seam to be calked.

The lower end of the tubular upright 2 has a chamber 8 which is designed to receive and house the calking blade or hammer 9. This blade 9 may be of any suitable or desired width and tapers toward its lower edge as is shown clearly in Fig. 1. This-blade 9 is carried by the lower end of a rod 10 which is mounted to reciprocate in the bore of the standard 2 and has a pitman 11 pivotally connected with its upper end, the other end-of said pitman being connected witha wrist pin 12 fixed to a crank disk 13 which is rotatably mounted in a partition 1 1 formed within the casing 1 and which divides the disk chamber 15 from another chamber 16 in which is rotatably mounted a shaft 17. A bevel cog 18 is fixed to the shaft 17 to rotate therewith and meshes with a larger bevel gear 19 which is fixed to one end of the shaft 20 which carries disk 13. It will thus be seen that when the shaft 17 is rotated motion will be imparted therefrom through the bevel gears 18 and 19 to the disk 13 and that the turning of this disk will operate through pitman 11 to reciprocate the rod 10 which carries the calking hammer 9.

The shaft 17 extends through the top of the casing 1 and has its terminal made an gular as shown at 21 to receive the actuating means for the shaft which may be a crank handle when the device is to be operated manually or a pulley when it is to be mechanically operated.

Mounted to rotate on an arm 22 which projects laterally from upright 2, is a reel 23. Two arms 22 are provided to support this reel as is shown clearly in Fig. 3,'said arms diverging for a certain distance and then extended parallel as shown at 22 havingtheir terminals notched to form bearings24c in which the trunnions 25 of the reel are designed to be rotatably mounted. This reel 23 is designed to have wound thereon the calking material which is in the form of a cotton thread 26 of any suitable size necessary for filling the seams to be calked.

Extending laterally from one side of the tubular standard 2 near its lower end is a housing 27 in which is mounted the thread feeding mechanism. This mechanism comprises a lever 28 which is fulcrumed at 29 on a projection 30 carried within the housing 27. This lever has a longitudinally extending slot 31 at one end and this slotted end extends through a longitudinal slot 32 in the rod 10 as is shown clearly in Fig. 2,

a pin 33 extending through the side walls of the slotted portion of rod 10 and through the slot 31 in the lever 28 as is shown clearly in Fig. l. A feeding finger 3% is pivotally connected with the outer end of lever 28 and tapers toward its free end, said end having an inturned spur 35 for engaging the thread 26 and forcing it forwardly under the hammer 9 when the finger 34: is moved forwardly and which releases from the thread when the finger moves rearwardly thereby preventin it from drawing back the thread 26 on its rearward movement.

The outer side wall of the housing 27 inclines downwardly and inwardly toward the lower end of the blade incasing chamber 8 and opens opposite the lower end of said chamber so that the thread 26 which is fed into the housing through a mouth 36 at its upper end will be passed under the hammer 9 during the operation of the machine as shown clearly in Fig. 1.

A spring 37 is carried by the outer face of the standard within the housing 27 and is here shown in the form of a plate spring fixed at one end to said standard with its free end bearing against the finger 34 and yieldably holding said finger in engagement with the thread 26, a guide being thus formed between the finger and the inclined wall of the housing as is shown clearly in Fig. 1.

It will thus be seen that when the rod 10 is reciprocated for lifting and lowering the hammer 9 the lever 28 will be correspondingly rocked and thereby impart a reciprocatory movement to the feed finger 34 so that when the rod 10 moves up the inner end of lever 28 will be carried with it and its .finger carrying end will be moved downwardly thereby forcing the thread 26 into the path of hammer 9 and when the rod moves downwardly the hammer will be lowered thereby engaging the thread and driving it into the seam to be calked and simul taneously with the lowering of the hammer the feed finger will be raised ready for the next feeding action. It will thus be seen that these two elements, the blade 9 and the finger 34 reciprocate alternately so that one will supply the material to be calked by the other;

It will of course be understood that the wheels 6 ope ate as guides for the machine, being inserted in the seam to be calked, the material being fed into the seams by the mechanism above described between the wheels, and driven thereinto by the hammer 9 so that one of the wheels will travel in the uncallted portion of the seam and the other in the calked portion thereof.

By constructing this machine in the manner above described, it will be seen that a strong, compact, simple mechanism is pro vided which may be easily lifted by the operator and carried from place to place and readily held in operative engagement with the structure to be calked. It is so small that it may be used in places which are ordinarily inaccessible to machines of this character and thus will be equally effective for use on the inside or outside of a vessel.

From the foregoing description, taken in connection with the accompanying drawin the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof. I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

I claim 1. in av calking machine, a supporting structure, guiding means therefor, a calking hammer, and afeeding device mounted for alternate reciprocation whereby the calking material is fed under the hammer ready for the driving blow thereof.

2.
